Hello, I’m going to start my first big sandponics build. I’m planning on converting a raised bed as my biofilter. It’s a pretty big build with cinder blocks and cement, it holds soil but I’m wondering if anymore reinforcement will be necerssary when swapping the soil out for sand.
My thinking is sand is heavier than soil and the constant weight change might cause problems over time. Like having a fish tank on a uneven surface; over time it can cause pressure on the glass which could break later (I’ve experienced this first hand with a big tank breaking months later).
Any advice or words of encouragement would be appreciated for this BIG project.
